Understanding ridge cap repair
Ridge caps protect the line where roof slopes meet. The ridge may also be part of a ventilation system, so a repair should account for both the covering and any underlying vent detail. The appropriate scope depends on the roof material and the extent of the damage. A contractor should check adjacent surfaces and fastening rather than replacing only the most visibly loose piece without assessing the rest of the affected ridge.
Signs to discuss
- Missing or lifted pieces along the roof ridge
- Visible ridge damage after a weather event
- Moisture concerns associated with the highest roof junction
What the work may involve
- Assess ridge covering, attachment, and adjacent roof material
- Check an existing ridge vent where applicable
- Discuss compatible replacement components and the repair boundary
Before agreeing to work
A ridge cap is not necessarily interchangeable with a standard field shingle or other roof component. Ask what product is suitable for the roof, how it will be fastened, and whether the ridge ventilation detail will be preserved or repaired. Describe the visible concern from the ground rather than attempting to inspect the ridge yourself.
Questions for your contractor
- Are the proposed caps compatible with the existing roof?
- Does the ridge vent also need attention?
- How much of the ridge should be repaired?
